Hi everyone, if you've been using the supplied EOS Utility with the EOS 40D to remote control the camera, you'll no doubt have found the remote manual focusing option. Great fun, but as soon as you close the focusing window to take the photo using the main 'pallette', the camera refocuses. You could set the focus remotely, then switch the lens to MF, but that's hardly living the remote dream is it?!

Here's a couple of solutions

1: Luckily the main palette remains active even with the manual focusing window open. So you can actually click the 'shutter release' graphic on the main palette even when the focusing window is open. And the lens won't refocus.

2: Set Custom Fn IV:1 to setting 2. With this setting the camera will only AF if you press the AF-ON button. Thanks to Chris Breeze (of DSLR Remote Pro fame) for this one!

3: Speaking of DSLR Remote Pro, this software lets you 'release' the shutter from the Live View preview window, without refocusing. It also lets you remotely control the focus of the lens even if the lens is set to MF. Pretty neat!
